# Ruby
A dynamic, interpreted language known for its elegant syntax.
## When to Use
- Web Development (Ruby on Rails)
- Scripting / Automation
- DevOps tools (Chef, Puppet)
- Prototyping
## Quick Start
```ruby
puts "Hello, World!"
class Greeter
def initialize(name)
@name = name
end
def say_hi
puts "Hi #{@name}!"
end
end
g = Greeter.new("Alice")
g.say_hi
```
## Core Concepts
### Everything is an Object
Numbers, strings, even nil are objects.
```ruby
1.odd? # => true
```
### Blocks & Iterators
Functional-style constructs for iteration.
```ruby
[1, 2, 3].each do |n|
puts n * 2
end
```
### Metaprogramming
Writing code that writes code (used heavily in Rails).
## Best Practices
**Do**:
- Optimize for developer happiness (readability)
- Use standard style guide (RuboCop)
- Use blocks for resource management (`File.open`)
**Don't**:
- Overuse monkey patching (modifying core classes)
- Write "Perl-ish" Ruby (keep it clean)
